Nothing. :-) Ie, the setchannel command work as good or as bad as before. > AFAICT, whenever you set the frequency, the tuner resets itself, so it > doesn't matter whether that frequency was working previously.

I'm just reporting my experience, I haven't (at this point at least) got any clue to what is causng this behaviour. Perhaps, AFC isn't working properly - impossible to tell. I do know that adding '-a on' or -a off' to the setchannel command don't change anything, AFAICT. > The seek fails because of some buffering problem between mplayer and > the device. I've had a terrible time getting this to work. Try this I will hasten to point out her that 'mplayer /dev/cxm0' works *most* of the time. It fails in perhaps one of five attempts. > cat /dev/cxm0 > somefile.mpg & > mplayer somefile.mpg For some reason, this command fails more often (2 out of 3 attempts) than the other command. > and I'll bet your seek problems will disappear (until you seek past > the end of the stream, obviously). How much did you bet? :-) Seriously, my guess is that the failures are related to this message in /var/log/messages: Oct 12 18:00:04 kg-quiet kernel: cxm0: encoder dma not enough buffer space free Oct 12 18:00:04 kg-quiet last message repeated 21 times > This sounds like an AFC problem. Try the setchannel with "-a on" and > make sure to do the cat & mplayer separately. I've tried, it doesn't change anything. Today, the pictures are better than yesterday. Reason unknown. -- Regards, Torfinn Ingolfsen
